"Asteroid" tablet pc will not boot!

Hey everyone, this is my first time using the forum so hi.
I am trying to fix a friends android tablet pc. I have never even heard of the make and no software comes with the device. It's a so called "Asteroid" tablet which will not get past the boot screen! it just gets stuck on the android logo with the dots going up and down the space ship. He said it worked for one day and then it broke. It does look very similar to the generic ones being sold on other websites and are just called "7 Inch Android 2.2OS Tablet with WiFi and Camera".

Any help is very much appreciated! Thanks
